Problem 2: A 60'x 30' mat foundation is shown in the following diagram. 35] a. Determine the net allowable bearing capacity of the mat foundation for 1.5 inch allowable settlement. b. Determine the maximum soil contact pressure and check if the mat is safe against bearing failure. c. Draw the free body diagram of the strip ACLK and adjust the forces to satisfy equilibrium for drawing the shear and moment diagrams. [Note: you do not have to draw the shear and moment diagrams] d. Determine the location and magnitude of the maximum negative moment between columns 1 and 2 . Show calculations. C NOTE: The column loads act at the center of the 2020 columns Problem 2: A 60'x 30' mat foundation is shown in the following diagram. 35] a.
